How DanRussell started their logo design journey

Summary

Ok, there's been some terrific submissions but I haven't found one that quite pulls it all together. Here's what we're now looking for:

* Leave the text out unless it's integral to the overall design. We will drop the icon beside the existing logo text
* Classic cruise ship shape, think Cunard
* Leaf shape coming out of funnel instead of smoke
* Style - less detail the better
* Icon must work at height of about 70 pixels

Company name

Clean Cruising

What inspires you and how do you envision the design for your business?

CleanCruising.com.au is the first cruise agency that offers "carbon neutral" cruising to passengers. When people book their cruise with us, we calculate the emissions their cruise would generate, and plant Australian native trees to offset the emissions at no extra cost. The site has been soft-launched and we have an existing logo and tagline but want to see some fresh ideas. We think an icon that combines a cruise ship and green theme could work well, ie trees replacing the smokestacks or something. Thanks in advance.
